  introduction

  The No. 712 Research Institute of China Shipbuilding Industry Corporation is located in Wuhan, which is a thoroughfare of nine provinces. It is the only military research institute specialized in ship electric propulsion equipment in China. It is mainly engaged in the research, development, design, testing and manufacturing of ship electric propulsion systems and equipment. . In 2009, in accordance with the special requirements of the 712 Institute, Dayu Electric provided 8 high and low voltage shared FZS generator set load test devices.

  1. Plan selection

  China Shipbuilding Industry Corporation 712 Research Institute AC and DC water resistance load equipment mainly provides adjustable load for generator set load test. Its main functions are:

  (1) Under 6~10KV high voltage, provide 1000~3000KW adjustable three-phase active load;

  (2) Under 440~690V, it provides adjustable three-phase active load with a maximum of 500A or less.

  The technical parameters of the load test device for the above requirements are:

  Rated power: 3000KW

  Rated voltage: 6.6KV

  Maximum working voltage: 11KV

  Rated adjustment range: 1000KW~3000KW

  Maximum resistance conditions: 11KV/1000KW

  Minimum resistance conditions: 400V/500A

  4 Conclusion

  Through many considerations and detailed inspections of related companies, CSIC combined with other products in the market to compare with other products in the market, and finally chose Dayu Electric's water load products. The FZS series generator load test device adopts liquid resistance and self-contained integrated design. It is mainly composed of liquid resistance box, electrode, lifting mechanism, plate exchanger, chemical pump, pipeline, control part, etc. The resistance liquid cooling device for the resistance load test control cabinet is installed in the water resistance load test control cabinet. It has a compact structure and does not occupy additional space; the resistance liquid cooling method adopts air-cooled heat exchangers, which can eliminate the resistance liquid circulation pump and cooling water circulation. Pumps, radiator towers, resistance liquid and cooling water circulation pipeline gates, and do not use cooling water, low investment; simple installation, convenient operation, good resistance liquid cooling effect, can meet the resistance liquid cooling required by the water resistance load during normal operation Cooling requirements. After years of field use, the FZS series generator load test device fully meets the needs of high-voltage high-power generators or other high-voltage power supply equipment for electrical performance testing. It is a simple, reliable, and cost-effective great power.
